Chemistry percentage

Hello how can i solve this any help ? 903

% w/w means weight per weight, so its disregarding the volume. It is the weight of solute divided by the weight of the solution (solute+solvent)

So I assume the equation would be 3/(3+9) x 100 = 25% so the answer is E

can u confirm?

The answer is D :smiling_face_with_tear: 21%.

I’d agree with E tbh, not sure how it would get D unless theres something involving molecular weight in the calculation?

damn I have no clue then😭, anyways I don’t think its required for the imat
